What is "lava lakes"

n. (lava lake English)

The Lava Lakes are a group of small lakes at the head of Lava Fork in the Boundary Ranges of northwestern British Columbia, Canada.

The Volcano, a cinder cone about north of the British Columbia-Alaska border above the eastern shore of the Lava Lakes, is the source for lava flows that overwhelm the lakes. These lava flows dam and form the lakes, hence giving their name.
